SEIRA.exe explores the essence of human emotions and connection through the virtual idol SEIRA. Amidst the distorted reality created by deepfake and AI technology, it asks whether love and emotions can still be real. The affection fans feel for a non-existent being, and the sense of loss that arises when that relationship breaks down, raises questions about humanity beyond mere pixels and code. This work prompts us to reconsider the meaning of art and human existence in an era where the boundaries between virtual and reality have dissolved.
